Problems with Norton Internet Security 2009 !!

 HI there.. I m using new version of norton internet security.. I m amazed by the use of system resources.. However, I found some glitches..

1. NIS 2009 doesn't detect the viruses in compressed files in real time.. I mean when I download any rar file, It doesn't detect until I open the file inside the rar or extract it..

2. When I ran a shields up test by GRC, I found port 554(Real time stream control protocol) was open and test failed.. 

3. Ads weren't blocked in Google Chrome, IE..

I use default settings.. If there is any solution to the above please reply..

Thanks
